A binary star system in the constellation Orion has an angular interstellar separation of 1.00 × 10–5 rad. If λ = 500 nm, what is the smallest diameter the telescope can have to just resolve the two stars?
A binary star consists of two stars orbiting each other. Suppose a binary pair is known to be 580.0 light years away from Earth. How far apart are the two stars from each other, in light years, if they can just be resolved by a telescope with an aperture of 50 cm (0.50 m), using visible light (l = 550 nm)? (1 nm = 1 x 10-9 m)
Pluto and its moon Charon are separated by 19600 km. An undergraduate researcher wants to determine if the 5.08 m diameter Mount Palomar telescope can resolve these bodies when they are 5.40×109 km from Earth (neglecting atmospheric effects). Assume an average wavelength of 545 nm.
To determine the answer, calculate the ratio of the telescope's angular resolution ?T to the angular separation ?PC of the celestial bodies.
